30k gallon IG pool-gunite
Jandy DE Filter: 150 gpm
Jandy Stealth Pump: 2.0 H.P
New pool here, contractor installed a Paramount Clear O3 ozonator. Everything I have read says I need a source of chlorine for the actual pool/body of water. Contractor does not seem to think so, but feel he is not sure himself. I am thinking I need a chlorinator after the water has passed the Ozone as the water returns to the pool so the water is sanitized. Any education here would be greatly appreciated.
